Nick Clegg is to call for a bail-like system of security bonds to tackle visa abuse today.
The Liberal Democrat leader will say that bonds would be paid as a cash guarantee from visa applicants who come in from high-risk countries, they would be repaid once the visitor leaves Britain.
In his first speech on immigration since he became Deputy Prime Minister, Mr Clegg will outline his vision for a "tolerant Britain, zero-tolerant of abuse" at the liberal think-tank, the Centre Forum.
It follows Ed Miliband's admission earlier this month that Labour "got [immigration] wrong" when they were last in power.
